Description

【０００１】
【発明の属する技術分野】
本発明は、振動発生，音声発生，ブザー音発生のような機能を備えた電磁誘導型アクチュエータ装置の改良、並びに、同電磁誘導型アクチュエータ装置を装備する携帯電話等を含む携帯用情報機器の改良に関するものである。
【０００２】
【従来の技術】
一般に、携帯電話やぺージャーまたは電子手帳等の携帯用情報機器は電磁誘導型アクチュエータ装置を振動発生，音声発生，ブザー音発生機器として装備することにより構成されている。
【０００３】
この種の電磁誘導型アクチュエータ装置としては、図１６並びに図１７で示すように円筒形のハウジング１を基枠とし、ボイスコイル２を内面側に取り付けたダイアフラム３を備え、そのボイスコイル２のリード線２ａ，２ｂをハウジング１の外部に引き出すと共に、ダイアフラム３をハウジング１の開放端１ａに嵌合せ固定し、更に、ボイスコイル２のリード線２ａ，２ｂをハウジング１の側壁より外方に突出する端子台１ｂの端子金具４ａ，４ｂとダイアフラム３の装着側で半田付け固定することにより、端子金具４ａ，４ｂを給電端子とする通電回路部が構成されている。
【０００４】
その通電回路部に対し、図１８で示すようにポールピース５と一体のマグネット６と、磁気ギャップＧをポールピース５との間に隔ててマグネット６をポールピース５と一体に保持するヨーク７とを備え、このヨーク７を薄板状のスプリング８ａ，８ｂで支持させてハウジング１の内部に組み付け、ボイスコイル２をポールピース５とヨーク７との磁気ギャップＧに挿置させて磁気回路部を形成し、更に、複数の放音孔９ａ，９ｂ…を設けたキャップ９をハウジング１の開放端１ｃに被着することにより電磁誘導型アクチュエータ装置として構成されている。
【０００５】
従来、その電磁誘導型アクチュエータ装置はダイアフラム３の取付け側を機器本体の筐体パネルに向け、キャップ９の取付け側を回路基板の板面に向けて端子金具４ａ，４ｂを回路基板の給電ランドと電気的に回路接続することにより携帯電話等の機器内に組付け装備されている。
【０００６】
その電磁誘導型アクチュエータ装置では、質量的に重い磁気回路部を振動させて加速度を得るため、磁気回路部より出る漏洩磁束が振動周波数に変調されて交流磁界となり、この交流磁界がダイアフラム３の取付け側から外部に出るところから、磁気記録カード類に対する影響が懸念される。
【０００７】
その交流磁界による影響を防ぐためには、ダイアフラム３の取付け側と反対側で漏洩磁束の少ないキャップ９の取付け側を機器本体の筐体パネルに向けて携帯電話等の機器内に組付け装備することが考えられる。
【０００８】
然し、上述した電磁誘導型アクチュエータ装置を唯単に逆向きに組み付けるだけでは、ボイスコイル２のリード線２ａ，２ｂを端子金具４ａ，４ｂに半田付けした側が回路基板の給電ランドと相対位置するため、この半田盛りが端子金具４ａ，４ｂを回路基板の給電ランドと電気的に回路接続するのに邪魔となる。
【０００９】
【発明が解決しようとする課題】
本発明は、ダイアフラムの装着側を回路基板の板面側に向け、その反対側を機器本体の筐体パネル側に向けて機器内に組付け装備することにより交流磁界による影響を抑えることを主眼とし、端子金具を回路基板の給電ランドと電気的に回路接続させて機器内に容易に組み付けられる電磁誘導型アクチュエータ装置を提供することを目的とする。
【００１０】
それに加えて、本発明は端子金具をハウジングの端子台に強固に取り付けし、しかも回路基板の給電ランドと電気的に確実に回路接続可能に備え、装置全体としてもコンパクトに組み立てられる電磁誘導型アクチュエータ装置を提供することを目的とする。
【００１１】
また、本発明は電磁誘導型アクチュエータ装置を振動発生，音声発生，ブザー音発生機器として装備しても、交流磁界による影響を抑えられる携帯電話等を含む携帯用情報機器を提供することを目的とする。
【００１２】
【課題を解決するための手段】

コの字状の嵌込み板部を中央に配置し、その嵌込み板部の片辺端から所定の隙間を保って相並行に折れ曲がるリード線接続用の平板部と、該嵌込み板部の他辺端から下り勾配の斜めに延びる板バネ部より上弦状に湾曲する給電ランド接続用の接点部とから形成した端子金具を備え、
端子台の天板部をリード線接続用の平板部と嵌込み板部の片端辺とから挟んで嵌込み板部を端子台の凹陥部に嵌め合せ、且つ、給電ランド接続用の接点部を端子台の底板部より突出させて両側板部で支持する嵌着構造で端子金具を端子台に取り付けることにより構成されている。
【００１５】
本発明の請求項４に係る電磁誘導型アクチュエータ装置においては、外側縁より突き出る突歯を備えて嵌込み板部の片端辺から両側に伸びるバネアーム部を端子金具に設けると共に、各バネアーム部の板厚に相当する隙間を隔て端子台の天板部と相対する受け桟を両側板部の内面に設け、そのバネアーム部を端子台の天板部と両側板部の受け桟との間に嵌め込んで突歯を両側板部の内面に弾圧係止する嵌着構造で端子金具を端子台に取り付けることにより構成されている。
【００１６】
本発明の請求項５に係る電磁誘導型アクチュエータ装置においては、バネ板部より上弦状に湾曲する接点部の先端から内側に折れ曲がって端子台の両側板方向に伸びる羽根板部を端子金具に設けると共に、その羽根板部を板バネ部の弾圧変位に伴って受止め支持する受け桟を両側板部の内面に設け、接点部をバネ変位可能に組み付ける嵌着構造で端子金具を端子台に取り付けることにより構成されている。
【００１７】
本発明の請求項６に係る電磁誘導型アクチュエータ装置においては、回路基板の給電ランドと接触する突条を接点部の円弧方向に沿って板面中央に設けた端子金具を備え付けることにより構成されている。
【００１８】
本発明の請求項７に係る携帯電話等を含む携帯用情報機器においては、請求項１〜６のいずれかに記載の電磁誘導型アクチュエータ装置を振動発生，音声発生，ブザー音発生機器として装備することにより構成されている。
【００１９】
【発明の実施の形態】
以下、図１〜図１５を参照して説明すると、図示実施の形態に係る電磁誘導型アクチュエータ装置は、基本的には一般例に係るものと共通する形態を備えて構成されている。その共通する基本形態は、図１６〜図１８で示すものの構成各部と同じ符号を用いて説明する。また、説明の便宜上、電磁誘導型アクチュエータ装置の装備向きを特定するのに、機器本体の筐体パネルと相対する側を上とし、回路基板の板面と相対する側を下とすることにより説明する。
【００２０】
その基本形態は、図１で示すように円筒状のハウジング１を基枠とし、ポールピース５と一体のマグネット６と、磁気ギャップＧをポールピース５との間に隔ててマグネット６をポールピース５と一体に保持する皿状のヨーク７とから磁気回路部を形成し、この磁気回路部を薄板状のスプリング８ａ，８ｂによるダブルサスペンス構造で支持させてハウジング１の内部に組み付けることにより構成されている。
【００２１】
また、ボイスコイル２を内面側に取り付けたダイアフラム３を備え、そのボイスコイル２をポールピース５とヨーク６との磁気ギャップＧに挿置させてダイアフラム３をハウジング１の開放端１ａで枠内に張設すると共に、ボイスコイル２のリード線２ａ（２ｂ）をハウジング１の側壁より外方に突出する端子台１ｂの端子金具４ａ（４ｂ）と電気的に接続し、更に、複数の放音孔９ａ，９ｂ…を設けたキャップ９をハウジング１の開放端１ｃに被着することにより構成されている。
【００２２】
その基本形態の下に、端子金具４ａ（４ｂ）として（以下、各金具の同じ構成部は単一の符号で示す。）は、回路基板の給電ランド（図示せず）と電気的に接触させる接点部４０をダイアフラム３の取付け側に設け、ボイスコイル２のリード線２ａと電気的に接続する平板部４１をキャップ９の取付け側に設けたものが備え付けられている。
【００２３】
その端子金具４ａ，４ｂを備えては、図２〜４で示すようにダイアフラム３よりハウジング１の外部に引き出されるボイスコイル２のリード線２ａ，２ｂをダイアフラム３の取付け側より反対方向に引き伸ばし、そのボイスコイル２のリード線２ａ，２ｂをキャップ９の取付け側で端子金具４ａ，４ｂの平板部４１と＋，−極に分けて電気的に接続することにより構成されている。
【００２４】
このように構成する電磁誘導型アクチュエータ装置は、携帯電話等を機器本体として組付け装備する際、図５で示すようにキャップ９の取付け側を筐体Ｃのインナーケース部ｃ_１と相対させ、ダイアフラム３の取付け側をインナーケース部ｃ_１との間でアウターケース部ｃ_２に取り付けられる回路基板Ｐの板面と相対させて筐体Ｃの内部に装備する逆向き型のものとして構成されている。
【００２５】
その電磁誘導型アクチュエータ装置では、漏洩磁束の少ないキャップ９の取付け側を筐体Ｃのインナーケース部ｃ_１に向け、漏洩磁束の多いダイアフラム３の取付け側を回路基板Ｐの板面に向けて機器内に組付け装備することから、交流磁界が筐体Ｃのインナーケース部ｃ_１より外部に漏れ出ることが抑えられるため、磁気記録カード類に対する交流磁界の影響を防げる。
【００２６】
これと共に、ボイスコイル２のリード線２ａ（２ｂ）が筐体Ｃのインナーケース部ｃ_１と相対するキャップ９の取付け側で端子金具４ａ（４ｂ）の平板部４１と＋，−極に分けて各々半田付け固定されているため、その半田盛りが端子金具４ａ（４ｂ）を接点部４１で回路基板Ｐの給電ランドｒ_１（ｒ_２）と電気的に回路接続するのに邪魔とならない。
【００２７】
その構成中、端子台１ｂは、図２〜図４で示すようにスリット１０を中央に設け、二つの＋極，−極用１１ａ，１１ｂと区分けすることによりハウジング１の側壁に設けられている。この端子台１１ａ，１１ｂに対し、ボイスコイル２のリード線２ａ，２ｂはスリット１０に通過させてキャップ９の取付け側に引き伸ばすと共に、＋，−極に分けて端子金具４ａ，４ｂの平板部４１と電気的に接続されている。
【００２８】
このリード線の配線構造では、スリット１０を介し、ボイスコイル２のリード線２ａ，２ｂを短い距離で安定よく配線させて端子金具４ａ，４ｂの平板部４１と確実に電気的に接続固定できる。
【００２９】
そのダイアフラム３より連続するリード線の引出し側においては、図６で示すように円弧状の湾曲した面取り部１２をスリット１０の奥側と連続させてハウジング１の外周縁に設けるとよい。この面取り部１２により、スリット１０に通過させてキャップ９の取付け側に引き伸ばすリード線２ａ，２ｂの絶縁被膜を損傷するのを防げる。
【００３０】
ダイアフラム３は、図２で示すようにハウジング１に固定される外周部３ａと、ボイスコイル（図示せず）の取り付けられる中央部３ｂとに分けて形成したものを備え、ボイスコイルのリード線２ａ，２ｂを外周部３ａと中央部３ｂとのフランジによる合わせ目から引き出させて一体に接合するとよい。
【００３１】
このリード線の引出し構造により、ボイスコイルのリード線２ａ，２ｂを外周部３ａの外側に配線できるため、ボイスコイル２のリード線２ａ，２ｂがハウジング１の内部に備えられる磁気回路部と接触しないよう配線できてリード線の断線を防げる。
【００３２】
端子台１１ａ（１１ｂ）は、図７並びに図８で示す（以下、各端子台の同じ構成部は単一の符号で示す。）如く中央奥に向かう凹陥部１００と、凹陥部１００の上下を区画する天板部１０１並びに底板部１０２と、天板部１０１並びに底板部１０２より大きい張出し寸法を持って凹陥部１００の左右を区画する両側板部１０３，１０４とから形成されている。
【００３３】
端子金具４ａ（４ｂ）は、リン青銅，チタン銅等の導電性を有する金属薄板を折曲げ形成したものが備え付けられている。この端子金具４ａ（４ｂ）は、図９〜図１２で示すようにコの字状の嵌込み板部４２を中央に配置し、その嵌込み板部４２の片辺端から所定の隙間を保つ立上り板部４３を介して相並行に折れ曲がるリード線接続用の平板部４１と、嵌込み板部４２の他辺端から下り勾配の斜めに延びる板バネ部４４より上弦状に湾曲する給電ランド接続用の接点部４０とから形成されている。
【００３４】
その端子金具４ａ（４ｂ）は、図１３で示すようにコの字状の嵌込み板部４２を橋絡板部４２ａより端子台１１ａ（１１ｂ）の凹陥部１００に向けて圧入し、端子台１１ａ（１１ｂ）の天板部１０１をリード線接続用の平板部４１と嵌込み板部４２の上端辺４２ｂとから挟み込で嵌込み板部４２を凹陥部１００の内部に嵌め合せ、給電ランド接続用の接点部４０を端子台１１ａ（１１ｂ）の底板部１０２より突出させて両側板部１０３，１０４で支持することにより取り付けられている。
【００３５】
この端子金具４ａ（４ｂ）の嵌着構造により、図１４で示すように嵌込み板部４２の上端辺４２ｂ並びに下端辺４２ｃが凹陥部１００の天板部１０１並びに底板部１０２に圧接すると共に、端子台１１ａ（１１ｂ）の天板部１０１をリード線接続用の平板部４１と嵌込み板部４２の上端辺４２ｂとで挟込み保持することから、嵌込み板部４２を凹陥部１００に向けて圧入するだけで、端子金具４ａ（４ｂ）を端子台１１ａ（１１ｂ）に強固に取付け固定できる。
【００３６】
それと共に、接点部４０を端子台１１ａ（１１ｂ）の底板部１０２より突出させて両側板部１０３，１０４で支持することにより、端子金具４ａ（４ｂ）を外方に張り出させないで端子台１１ａ（１１ｂ）の内部に収めて取り付けられるため、装置全体としてコンパクトなものに組み立てられる。
【００３７】
その端子金具並びに端子台の構成に加えて、端子金具４ａ，４ｂには図１０並びに図１３で示すように複数の突歯４５ａ…，４５ｂ…を外側縁より突き出すことにより嵌込み板部４２の上端辺４２ｂから両側に伸びて脇空きのバネアーム部４６ａ，４６ｂが設けられている。これに対し、端子台１１ａ（１１ｂ）には、図８並びに図１３で示すように各バネアーム部４６ａ，４６ｂの板厚に相当する隙間を隔て天板部１０１と相対する受け桟１０５ａ，１０５ｂが両側板部１０３，１０４の内面に設けられている。
【００３８】
この構成各部では、端子金具４ａ（４ｂ）のバネアーム部４６ａ，４６ｂを端子台１１ａ（１１ｂ）の天板部１０１と両側板部１０３，１０４の受け桟１０５ａ，１０５ｂとの間に嵌め込んで突歯４５ａ…，４５ｂ…を両側板部１０３，１０４の内面に弾圧係止することから、端子金具４ａ（４ｂ）を端子台１１ａ（１１ｂ）に一層強固に取付け固定できる。
【００３９】
また、端子金具４ａ（４ｂ）には羽根板部４７がバネ板部４４より上弦状に湾曲する接点部４０の先端から内側に折れ曲がって端子台１１ａ（１１ｂ）の両側板方向に伸びるよう設けられている。これに対し、端子台１１ａ（１１ｂ）には端子金具４ａ（４ｂ）の羽根板部４７を板バネ部４４の弾圧変位に伴って受止め支持する受け桟１０６ａ，１０６ｂが両側板部１０３，１０４の内面に設けられている。
【００４０】
この構成各部では、図１５で示すように接点部４０を回路基板Ｐの給電ランドｒ_１（ｒ_２）と圧接するに伴って、端子金具４ａ（４ｂ）がバネ変位できると共に、受け桟１０６ａ，１０６がストッパーとして羽根板部４７を押えることにより給電ランドｒ_１（ｒ_２）に対する圧接力を強く保てて端子金具４ａ（４ｂ）による電気的接触を確実に取れる。
【００４１】
なお、羽根板部４７の受け桟１０６ａ，１０６はバネアーム部４６ａ，４６ｂの受け桟１０５ａ，１０５ｂと背合わせで一体に設けられている。また、端子金具４ａ（４ｂ）の嵌込み装着時に、接点部４０の突出姿勢を位置決め規制する羽根板部４７の受け桟１０７ａ，１０７ｂが両側板部１０３，１０４の下端辺に沿って内側に設けられている（図８並びに図１３参照）。
【００４２】
上述した他に、端子金具４ａ（４ｂ）には、回路基板Ｐの給電ランドｒ_１（ｒ_２）と接触する突条４８が接点部４０の円弧方向に沿って板面中央に設けられている。この突条４８は、リブとして接点部４０を補強でき、接点部４０を回路基板Ｐの給電ランドｒ_１（ｒ_２）と強く接触させても変形を生じないことにより給電ランドｒ_１（ｒ_２）に対する端子金具の電気的接触を一層確実に取れる。
【００４３】
このような端子金具を備える電磁誘導型アクチュエータ装置では、ダイアフラム３の取付け側を回路基板Ｐの板面に向け、その反対側を筐体Ｃのパネル面に向けて機器内に組付け装備することから、交流磁界が筐体Ｃの外部に出るのを抑えられることにより、磁気記録カード等に対する影響を防げる。
【００４４】
それと共に、端子金具４ａ（４ｂ）を回路基板Ｐの給電ランドｒ_１（ｒ_２）と電気的に回路接続させて機器内に容易に組み付けられ、また、端子金具４ａ（４ｂ）をハウジング１の端子台１１ａ（１１ｂ）に強固に取り付けられることにより、回路基板の給電ランドｒ_１（ｒ_２）と電気的に確実に回路接続でき、装置全体としてもコンパクトに組み立てられる。
【００４５】
なお、本明細書中で用いた用語及び表現は本発明を判り易く説明するために用いたものであり、その用語及び表現は本発明の技術的思想を何ら限定するものでない。仮に、限定的な用語及び表現を用いたからといって、そのことにより、上述した本発明の形態と均等なもの或いはその一部を排除する意図はない。
【００４６】
特に、電磁誘導型アクチュエータ装置の組付け向きについて機器本体の筐体パネルと相対する側を上とし、回路基板の板面と相対する側を下とすることにより説明したが、これは飽くまで説明の便宜上であり、端子台の天板部並びに底板部等の表現も同様である。このため、権利が要求されている本発明の範囲内で種々の表現の変更を加えることが可能である。
【００４７】
